nodetool sethintedhandoffthrottlekb
Sets hinted handoff throttle in KB/sec per delivery thread.
When a node detects that a node for which it is holding hints has recovered, hints are sent to that node. This command sets the maximum sleep interval per delivery thread after delivering each hint. The interval shrinks proportionally to the number of nodes in the cluster. For example, if there are two nodes in the cluster, each delivery thread uses the maximum interval; if there are three nodes, each node throttles to half of the maximum interval, because the two nodes are expected to deliver hints simultaneously.
